15 a plan view and Fig. 2 a fragmentary side elevation of a reaping machine embodying the invention, Fig. k,3 `is a fragmentary elevation of the rotary cone as yviewed in the direction indicated by the arrow A Fig. 1. Referring to the drawings, the rotary cone 1 is secured on a shaft 2 extending axially of the cone and. journalled at the apex end of the cone in a bearing 3 carriedon the outer end of thereaper cutter 4. The rear portion of the shaft 2 exterior of the cone 1 is sleeved by a non-rotary tube 5 on the forward end of which is secured a sun pinion .wheel 6 meshing with planetary pinion wheels 7, 8 mounted on a bar- 9 carried by the cone 1. The pinion wheels 7, 8 are provided with crankpins 7 8 respectively, operatively en-` gaged by the inner ends of rods 10, 11 the outer ends of which are guided in apertures 12 in the lateral wall of the cone. v The arrangement is such that, in the rotation of the cone 1 in the'direction indicated by the arrow B, the rods 10, 11 are reciprof 45 train heavy crop not influenced in the ordinary way. by the cone. Y

The cone 1 is driven from the axle shaft 13 0f the reaper through a train including a sprocket wheel 14 secured on the shaft 13 and wrapped bya chain.15 which also Wraps a sprocket pinion 16 secured on one end of a countershaft 17 journaljled within 'a tube 18 and carrying on its other end a bevel pinion 19 meshing with a bevel pinion20 secured on the rear end of the cone shaft'2, the pinions 55 19, 20 beingenclosed in a casing 21 which rigidlyinterconnects the tubes 5, 18. The

tube 18 is so supported from the seat-supportf ing structure 22 of the reaper that it is free f to perform slight tiltingmovement whenthe cutter 4 is raised in the usual manner by de` pression of the usual foot-lift lever 23. To cause the tube 18 tofparticipate in the move-, ments ofthe lever 23 a link 24 connectedto the tube 18 at 25 is connectedto one arm 26 65 y `of a bell-crank lever 26,27- whose other arm 27 is connected through a link 28 tothe footj liftlever 23.

Iclaim: f l j I 1. In an agricultural reaping machine, the combination with a. cutter of` a forwardly di` rected rotary cone located at the outer end of said cutter, and crop-entraining means in- A cluding sun-and-planetrgear mechanism incorporated in said cone androds adapted to be projected radially of said cone beyond the Y outer surface of said cone.

2. In an agricultural reaping machine, the

located at Vthe outerend of saidcutter and car ried by said shaft, a nonrotary tube sleeving said shaft, and crop-entraining means incorporated in said cone and including a sun pinion secured on saidtube, planetary pinions meshing with said sun pinion and carried by said cone, rods Vreciprocable radially of said i. 90 l cone and operatively connected to said planetary pinionsso that, in the rotation of said cone, the outerends of said rods are projected beyond the outer surface of said cone, substantially as and for the purpose set forth. l In testimony whereof I have signed my name to this specification.V c n f Y Y ALEXANDER SANDS?
